Beginners Help

[waveydavey]

My Son is about to embark on his flying career with a 450 I have just built him. I don't know an awful lot about electrics but what I do know is I don't want him getting carried away and giving it a handful and see the heli disappear into the distance. Can I control the amount of lift I let him have by manipulating the throttle and pitch curves. Anyone tried this method? Cheers in advance

Get him to practice on the sim for a while as the 450 can b a bit of a beast if your not used to it, u can dial in some expo and dual rates at first this may help

u can fine tune the pitch / throttle curves for a new flyer.

You can decrease the total pitch range in the swash menu on the radio.

You can alos control the headspeed with the throttle curve.

hi
i may be wrong totally on this , can u not connect to his tx with a buddy cable to your tx so u can take control at the flick of a switch if needed till he gets used to it .

I could if I wasn't still on 35Meg with no real hurry to change. I thought about getting a DX7 but I'm not sure he'll stick with it, I just want to see if he has the want to learn. If not I'm quite happy to fly it about for him, lovely little thing. I fitted a KDS800 Gyro last night, ebay £20 and it's absolutely superb. I was really not up for having a 450 but I really got a feel for it last night.

It's the same as a nitro just a different power source. Just lower the pitch curve - but don't go too much otherwise it can become a bit to slow to control (have to chase it).


I recommend about 10-11 degrees of collective pitch to start with at max and min.


You don't need a crazy throttle curve either, but too low can cause it to become less stable. Try to keep the throttle curves as flat and as consistent as possible, when the motor RPM changes in the air it causes the tail to struggle against the torque.

Edit: As Martin says below maybe -2 - -3 degrees negative pitch would suit your son more to start with, have a try with both. Remember to tell him not to hit pitch down too fast.

Yes indeed you can control the pitch on the blades and the total amount of throttle via the pitch and throttle curves, and by using the swash mix.

Personally I am only using -2 degrees of pitch at low stick and +10 at high stick.

Cheers guys I was more worried about him giving it a handful and seeing it dissapear towards the moon. I suppose what I could do is reduce the -ve pitch to say what martin has suggested and if it does go skyward i can take the Tx and bring it back for him. I may be worrying about it too much, he can fly on the sim, land and takeoff without any trouble so I may be being a bit too cautious.

[Mart61]

Give the lad a fortnight and he'll be out-flying you.

When I was teaching Mark, I found a clip round the ear if he got too ambitious very effective!

One thing that might help as well is to reduce the angle of the curve just above mid stick so that the hover range is a milder slope and little stick movements won't cause as much up and down movement of the heli. So your pitch curve begins to look ever so slightly like a backwards and sideways 'S' if that makes any sense. Basically it starts at zero, goes up and then levels off a bit after the mid stick point and then goes back up again to whatever the max is you want at the top.

I like that, nice idea. Cheers

If he can fly fine in the sim I'm sure he will be just fine in real life, besides if the worst case did happen and he forgot something, and it kept climbing just grab the TX and land it yourself .

Thats my back up plan, cheers

Well thinking about it, its gotta be better to suddenly shoot upwards than it is to to suddenly shoot downwards Lol
